Twice today I have entered Catan to be greeted by a message asking if I want to return to a game. Then it ends up barring me for 5 minutes for leaving a game improperly. I am very protective of my 3 gold star rating: I do not abandon a game, even if I am losing horribly! After the first warning I wondered if I had failed to log out of the game properly, so I was very careful to exit properly. I still got the message the next time in.
This has dropped my completion % from 98 to 96.
